Die Odyssee der Pygmäen. Eine prekäre Figur auf den neuzeitlichen Spieltischen anthropologischer Differenz

Due to the impacts of postcolonialism, social and cultural anthropology has been dealing intensively with the possibilities and limits of representing "other” human beings and their meaningful worlds. Scholars such as George Marcus, James Clifford or Clifford Geertz have discussed ways of improving anthropological methods of representation without, however, fully raising questions about the quality and validity of the objects represented and the very idea, that they could be “represented”. Thus, despite attempts to purify classical anthropological categories, substantialized presences (“Humans”, “Others”, “Pygmies” etc.), various forms of binary oppositions (us–them, culture–nature, human–animal) as well as certain epistemological modes/ logoi (representation, interpretation) have been rehearsed until today. The research aims to dissect and challenge the metaphysical outputs of the “anthropological machine” (Giorgio Agamben). I intended to solve these from their apparent familiarity as representable identities or differences in order to investigate their genealogy. In Derrida’s and Foucault’s understanding, genealogy becomes manifest mainly in the “blind spots” (Derrida) or “anomalies” (Foucault) between differences, at the borders of identities. As an analytical guideline, the research uses on one concrete metonym for the Derridean blind spot, one incorporation of a Foucauldian Other, namely pygmy narratives within early modern and 19th century imaginings. “Pygmies” have been part of both Western mythology and anthropological reflection since the antiquity and finally became “ethnographical facts” within an evolutionary anthropology in the 19th century during the European exploration of Africa. Throughout this veritable Odyssey, they were mostly precarious “category-jammers” (Timothy Beal), occupying the impossible middle grounds within (proto)anthropological classification. Thus, along with the early modern wild men, enfants sauvages or the apes of proto-primatology, the pygmies of the Homeric myth, as a catalyst for the negotiation of categories, played a decisive role in early modern and 19th century conceptions of the human. Through the precarious Pygmies, concrete socio-historical materializations of Identities (human, European), differences (human–animal etc.), as well as the accompanying logoi which vindicate these as pseudo-entities, appear evident. The research aims to read and write the history of early modern and 19th Century anthropology through one of its many classificatory constituting Others. It thus contributes to a discipline that for a long time has examined concrete systems of knowledge and the genealogy of classification in general. One might call it an “anthropologization” of anthropology.

Gadoxetate uptake as a possible marker of hepatocyte damage after liver resection-preliminary data

AIM: To determine the feasibility of evaluating surgically induced hepatocyte damage using gadoxetate disodium (Gd-EOB-DTPA) as a marker for viable hepatocytes at magnetic resonance imaging (MRI) after liver resection. MATERIAL AND METHODS: Fifteen patients were prospectively enrolled in this institutional review board-approved study prior to elective liver resection after informed consent. Three Tesla MRI was performed 3-7 days after surgery. Three-dimensional (3D) T1-weighted (W) volumetric interpolated breath-hold gradient echo (VIBE) sequences covering the liver were acquired before and 20 min after Gd-EOB-DTPA administration. The signal-to-noise ratio (SNR) was used to compare the uptake of Gd-EOB-DTPA in healthy liver tissue and in liver tissue adjacent to the resection border applying paired Student's t-test. Correlations with potential influencing factors (blood loss, duration of intervention, age, pre-existing liver diseases, postoperative change of resection surface) were calculated using Pearson's correlation coefficient. RESULTS: Before Gd-EOB-DTPA administration the SNR did not differ significantly (p = 0.052) between healthy liver tissue adjacent to untouched liver borders [59.55 ± 25.46 (SD)] and the liver tissue compartment close to the resection surface (63.31 ± 27.24). During the hepatocyte-specific phase, the surgical site showed a significantly (p = 0.04) lower SNR (69.44 ± 24.23) compared to the healthy site (78.45 ± 27.71). Dynamic analyses revealed a significantly lower increase (p = 0.008) in signal intensity in the healthy tissue compared to the resection border compartment. CONCLUSION: EOB-DTPA-enhanced MRI may have the potential to be an effective non-invasive tool for detecting hepatocyte damage after liver resection.

From Broadstone to Zackenberg

Ecological networks are typically complex constructions of species and their interactions. During the last decade, the study of networks has moved from static to dynamic analyses, and has attained a deeper insight into their internal structure, heterogeneity, and temporal and spatial resolution. Here, we review, discuss and suggest research lines in the study of the spatio-temporal heterogeneity of networks and their hierarchical nature. We use case study data from two well-characterized model systems (the food web in Broadstone Stream in England and the pollination network at Zackenberg in Greenland), which are complemented with additional information from other studies. We focus upon eight topics: temporal dynamic space-for-time substitutions linkage constraints habitat borders network modularity individual-based networks invasions of networks and super networks that integrate different network types. Few studies have explicitly examined temporal change in networks, and we present examples that span from daily to decadal change: a common pattern that we see is a stable core surrounded by a group of dynamic, peripheral species, which, in pollinator networks enter the web via preferential linkage to the most generalist species. To some extent, temporal and spatial scales are interchangeable (i.e. networks exhibit ‘ergodicity’) and we explore how space-for-time substitutions can be used in the study of networks. Network structure is commonly constrained by phenological uncoupling (a temporal phenomenon), abundance, body size and population structure. Some potential links are never observed, that is they are ‘forbidden’ (fully constrained) or ‘missing’ (a sampling effect), and their absence can be just as ecologically significant as their presence. Spatial habitat borders can add heterogeneity to network structure, but their importance has rarely been studied: we explore how habitat generalization can be related to other resource dimensions. Many networks are hierarchically structured, with modules forming the basic building blocks, which can result in self-similarity. Scaling down from networks of species reveals another, finer-grained level of individual-based organization, the ecological consequences of which have yet to be fully explored. The few studies of individual-based ecological networks that are available suggest the potential for large intraspecific variance and, in the case of food webs, strong size-structuring. However, such data are still scarce and more studies are required to link individual-level and species-level networks. Invasions by alien species can be tracked by following the topological ‘career’ of the invader as it establishes itself within a network, with potentially important implications for conservation biology. Finally, by scaling up to a higher level of organization, it is possible to combine different network types (e.g. food webs and mutualistic networks) to form super networks, and this new approach has yet to be integrated into mainstream ecological research. We conclude by listing a set of research topics that we see as emerging candidates for ecological network studies in the near future.

Rezension zu: Irini Katsirea, Public Broadcasting and European Law

Public broadcasting has always been a regulatory field somewhat zealously guarded within the nation states' sphere and kept willingly untouched by regional or international rules. Values inherent to the role of public broadcasting, such as cultural and national identity, social cohesion, pluralism and a sustained public sphere, were thought too critical and too historically connected with the particular society to allow any "outside" influence. Different regulatory models have emerged to reflect these specificities within the national boundaries of European countries. Yet, as media evolved technologically and economically, the constraints of state borders were rendered obsolete and the inner tension between culture and commerce of the television medium became more pronounced. This tension was only intensified with the formulation of a European Community (EC) layer of regulation, which had as its primary objective the creation of a single market for audiovisual services (or as the EC Directive beautifully put it, a "Television without Frontiers"), while also including some provisions catering for cultural concerns, such as the infamous quota system for European and independent productions. Against this backdrop, public broadcasting makes a particularly intriguing subject for a study of regulatory dilemmas of national versus supranational, integration versus intergovernmentalism, culture versus commerce, intervention versus liberalisation, and all this in the dynamic setting of contemporary media. The present paper reviews Irini Katsirea's book PUBLIC BROADCASTING AND EUROPEAN LAW and seeks to identify whether all elements of the complex governance puzzle of European public service broadcasting rules are analytically well fitted together.

The Trade Versus Culture Discourse: Tracing its Evolution in Global Law

The intensified flows of goods, services, peoples and ideas across borders intrinsic to globalization have had numerous and multi-faceted effects. Those affecting culture have been perhaps the most controversial, as it is more often than not difficult to identify the spill-overs across economic and non-economic areas and across borders, as it is equally hard to qualify the effects of these spill-overs as positive or negative. The debate also tends to be politically and even emotionally charged, which has so far not proven advantageous to establishing a genuine dialogue, nor to finding solutions. This contention and the divergent interests of major players in the international community have been reflected in the institutions and rules of global law. It is the objective of this chapter to explore this institutional architecture, in particular its main (and opposing) constituent fora of the World Trade Organization (WTO) and the United Nations Educational Social and Cultural Organization (UNESCO). The chapter traces the evolution of these institutions and their interaction over time, as well as the underlying objectives, demands and strategies of the key proponents in the trade versus culture discourse, which ultimately shaped the existent law and policy. The chapter concludes with an appraisal of the present state of affairs situating the discussion into the contemporary global governance landscape.

The origin of oriented lakes: evidence from the Bolivian Amazon

The presence of hundreds of rectangular and oriented lakes is one of the most striking characteristics of the Llanos de Moxos (LM) landscape in the Bolivian Amazon. Oriented lakes also occur in the Arctic coastal plains of Russia, Alaska and Canada and along the Atlantic Coastal Plain from northeast Florida to southeast New Jersey and along the coast of northeast Brazil. Many different mechanisms have been proposed for their formation. In the LM, Plafker's (1964) tectonic model, in which subsidence results from the propagation of bedrock faults through the foreland sediments, is the most accepted. However, this model has not been verified. Here, we present new results from stratigraphic transects across the borders of three rectangular and oriented lakes in the LM. A paleosol buried under mid-Holocene sediments is used as a stratigraphic marker to assess the vertical displacement of sediments on both sides of the alleged faults. Our results show that there is no vertical displacement and, therefore, that Plafker's model can be ruled out. We suggest that, among all the proposed mechanisms behind lake formation, the combined action of wind and waves is the most likely. The evidence from the LM provides new hints for the formation of oriented lakes worldwide.

Luxurious Merovingian Textiles Excavated from Burials in the Saint Denis Basilica, France, 6th-7th century

A new examination of the textile fragments found in the Merovingian burials in the basilica of Saint Denis, near Paris, has recently underscored the diversity of fabrics used to make garments in which members of the royal court were buried. Among them, some woolens of fine quality had been dyed with indigotin. The most astonishing fibre found belongs to a mixed textile (not skin) with beaver fibers and wool. Silks contained shellfish purple and in one case kermes? Two dyestuffs associated with royalty and privilege. Along with this was large number of gold threads, probably produced locally and that were used in tablet-woven borders or for embroideries. In addition, several figured silks, of oriental origin, testify to the importance of this "foreign" material and the taste for textiles woven with complex techniques and probably what had originally had beautiful designs. Although none of these designs have been preserved and many colors have been greatly damaged, the technical characteristics of the remnants indicate proveniences as far as Byzantium, Sassanid Persia and the Chinese court. Such precious textiles show the high social status and political power of the Merovingian court, a testament to their ability to access such luxurious and costly textiles through diplomacy and/or trade with other powerful empires. The examination of these rare textiles along with other fine silks and luxury objects from the same period found in France expand our view of the fundamental role of textiles in the political sphere of this early period of European history.

Essential Properties and Coinciding Objects

How can a parcel of matter, or collection of particles, simultaneously compose three different objects, characterized by different modal properties? If the statue is gouged it still exists, but not exactly that piece of gold which originally occupied the statue's borders, and the (mass of) gold within that piece can survive dispersal, while the piece cannot. The solution to this "problem of coinciding objects", this paper argues, is that there is, in that space, only the statue. The properties which the piece and the mass supposedly must have, to go on being, are not properties which anything can have necessarily or essentially. Not even having that origin can be essential. There is no object of which the statue is composed, though there are objects (viz., gold atoms) and a kind of stuff (viz., gold) of which it is composed.

Musiktraditionen im Kontext moderner Globalisierungsprozesse und globaler Denkkonzepte

The documentation of music cultures and the research in and on “classic” regions like India, Indonesia, and Sub-Saharan Africa still plays a central role within ethnomusicological research. However, given the increasing impact of global processes, the central guiding questions of the discipline have undergone profound changes in recent years. Approaches towards globalization are highly varied: One dominant perspective – which can be described as “skeptical” – has equated globalization with musical homogenization. This perspective is still apparent in approaches in European folk music research, which focus on the preservation of “traditional” cultures. Besides hyperglobal perspectives, which perceive the emergence of global networks (hypermedia, mass media, cultural organizations) as a positive development, one can predominantly observe the emergence of transformationalist approaches in recent decades: Global interconnectedness is viewed as a (neutrally perceived) basis for the emergence of new musical structures here. The transformation of the discipline is also apparent in the shift of the historical perspective. Comparative Musicology had already developed a global-historical perspective, which, however, became problematic due to the lack of contextualization. This might explain the subsequent distanced stance taken towards global concepts. Yet the focus on oral cultures also neglected deeper analysis of the historical dimension. At present, one can observe the emergence of a – albeit highly differentiated – change of perspective. While the Anglo-American approaches encourage the development of a specifically ethnomusicological-historical methodology, this separation between ethnomusicological and historical topics is perceived as racist in countries like South Africa. Starting out with an analysis of the concept of canonization in ethnomusicology, this article not only provides an overview of the aforementioned approaches and developments, but also discusses the integration of these processes into ethnomusicologically informed music pedagogical teaching material – within both a school and university context.

Who, When, and Why – Investigating Cultural Footprints at Early Iron Age Tel Kinrot

Ancient Kinneret (Tel Kinrot [Hebrew]; Tell el-‘Orēme [Arabic]) is located on a steep limestone hill on the northwestern shores of the Sea of Galilee (map ref. 2508.7529 [NIG]; 35.56/32.87 [WGS84]). The site, whose settlement history began sometime during the Pottery-Neolithic or the early Chalcolithic period, is emerging as one of the major sites for the study of urban life in the Southern Levant during the Early Iron Age (c. 1130–950 BCE). Its size, accessibility by major trade routes, and strategic location between different spheres of cultural and political influence make Tel Kinrot an ideal place for studying the interaction of various cultures on urban sites, as well as to approach questions of ethnicity and regionalism during one of the most debated periods in the history of the ancient Southern Levant.

Circumferential distribution of the neointima at six-month and two-year follow-up after a bioresorbable vascular scaffold implantation: a substudy of the ABSORB Cohort B Clinical Trial

Aims: To investigate the extent and the circumferential distribution of the neointima tissue developed following an Absorb bioresorbable vascular scaffold (BVS) implantation. Methods and results: Twenty-three patients who were treated with the Absorb BVS and had optical coherence tomographic examination after scaffold implantation, at six-month and at two-year follow-up, were included in the current analysis. The lumen and the scaffold borders were detected and the circumferential thickness of the neointima was measured at one degree intervals. The symmetry of the neointima was defined as: minimum/maximum thickness. The lumen area was decreased at six months compared to baseline but it did not change between six-month and two-year follow-up (baseline: 7.49 [6.13-8.00] mm2, six months: 6.31 (4.75-7.06) mm2, two years: 6.01 [4.67-7.11] mm2, p=0.373). However, the mean neointima thickness (six months: 189 [173-229] μm, two years: 258 [222-283] μm, p<0.0001) and the symmetry index of the neointima (six months: 0.06 [0.02-0.09], two years: 0.27 [0.24-0.36], p<0.0001) were increased at two years. Full circumferential coverage of the vessel wall by neointima tissue was seen in 91% of the studied frames at two years. Conclusions: This study demonstrates that after an Absorb BVS implantation neointima tissue develops that covers almost the whole circumference of the vessel wall. In contrast to the metallic stents, the neointima tissue does not compromise the luminal dimensions. Further research is required to evaluate the neointimal characteristics and assess the potential value of the device in passivating high-risk plaques.
